Thank you for your interest in the supplementary material accompanying the article "Lost Seoul?: Assessing 
Pyongyang's Other Deterrent." Everything necessary to understand and replicate the results in the article 
and appendix and to make use of the model is included in the supplemental material.

If you make use of the model or underlying data in your research, please cite the following article:

Nicholas D. Anderson and Daryl G. Press, "Lost Seoul? Assessing Pyongyang's Other Deterrent," The Texas 
National Security Review, Vol. 8, No. 3 (Summer 2025), pp. 8-27.

The files included in the supplemental material are:

1. Lost Seoul - Appendix.pdf -- This is the appendix that accompanies the article.

2. Lost Seoul - Model.xlsx -- This is the main model used to produce the results presented in the article 
   and appendix.

3. Lost Seoul - Model (simulation).xlsx -- This is the model used to produce the simulation results 
   presented in the article and appendix. It is identical to the main model (#2, above), but is set up to 
   run Monte Carlo simulations.

4. Lost Seoul - Supplementary Data.xlsx -- This is a collection of data files that make up and inform the 
   analysis presented in the article and appendix, including the main article figures; full simulation 
   results; the resilient HARTS excursion; appendix tables; and HARTS data.

5. Lost Seoul - HARTS Data.kml -- This is a Google Earth Pro file that maps each and every North Korean 
   hardened artillery site (HARTS) included in the analysis and data (#4, above).
